Gandharva
The Gandharvas (Sanskrit: गन्धर्व) are male nature spirits and husbands of the Apsaras. Some are part animal, usually a bird or horse. They have superb musical skills. They guard the Soma and make beautiful music for the gods in their palaces. Gandharvas are frequently depicted as singers in the court of the gods.
Gandharvas in the historic sense acted as messengers between the gods and humans. In Hindu law, a gandharva marriage is one contracted by mutual consent and without formal rituals.
Gandharvas are mentioned extensively in the epic Mahabharata as associated with the Devas (as dancers and singers) and with the Yakshas, as formidable warriors. They are spread across various territories.
